CHARLES G. MOLEOD, OF WORCESTER, MASSACHUSETTS.

JOINT FOR WIRE, WIRE Roos, CABLES, etc.

SPECIFICATION forming part of Letters Patent No. 328,502, dated October 2OI 1885.

Application filed April 27, 1885.

To all whom t may concern:

Be it known that I, CHAnLns G. MoLnoD, of Vorcester, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Couplings for Vires Employed for Conducting Electric and Sound Currents; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which- Figure l represents'a plan view of my aforesaid improved coupling. Fig. 2 represents an end view of the same. Figs. 3 and 4 rep resent central longitudinal and central transverse sections, respectively, of the coupling` shown in Fig. l, and Figs. 5, 6, 7, and 8, detail views thereof, hereinafter more fully described.

The object of my invention is to provide a means whereby the ends of telegraph wires and similar strands employed for conducting electric and sound currents may be better united and said currents more perfectly trans` niitted from one section of wire to another than by the use of couplings now employed for the saine purpose.

It consist-s in the combination of a copper lining` made in two or more longitudinal sections, which its over the abutting ends of the wires, with a double tapered screw made hollow and also in two or more longitudinal sections, and suitable nuts adapted to be turned up over said tapered screws to contract the same and its copper lining to hold the abutting ends placed therein, as hereinafter more fully set forth.

To enable those skilled in the art to which my invention appertains to make and use the same, I will proceed to describe it more in detail.

In the drawings, A represents the centralscrew part, hereinbefore referred to, which is provided with the tapered threaded parts A A', tapering toward the ends thereof. Said screw part A is, in this instance, made in three longitudinal sections, a a a; but I do not limit myself to this number. It is also provided with a central longitudinal opening,

b, to receive the abutting ends c c of the wires to be united and the copper lining d. Said copper lining, which covers the abutting ends of the wires, as shown in Fig. 3, is recessed into the screw part A in this instance, and also made in three longitudinal sections, as represented in Fig. 4. If preferred, however, it may extend the whole length of the screw part, and be made in two or more than three sections.

After the lining and screw part have been placed over the abutting ends c c of the wires they are held in position and contracted to securely hold said ends c c by turning the tapering nuts B B up over the tapered screws A A', as shown in Fig. I, said operation being facilitated by means of the square parts B B formed on said nuts, over which a wrench may be fitted, the screw part also being provided with a central hub, A2for the same purpose.

By thus fastening the ends of wires it will be seen that the operation may be quickly and conveniently performed, while at the same time they are held in a very secure and permanent manner.

It is also obvious that by the use of a copper lining over the abutting ends of the wires, as heinbefore described, the electric or sound currents transmitted over said wires are assisted rather than retarded in passing from one section of wire to another, on account of the greater conductive power of the copper over the iron or steel of which the wires are composed.

Having described my improvements in couplings for wires, what I claim therein as new and of my invention, and desire to secure by Letters Patent, is-

Ihe improved coupling for telegraph and similar electric and sound conducting wires, consisting of the tapered screw part A, made hollow and in sections, and the tapered nuts B B, in combination with the copper lining d, also made in sections, substantially as and for the purpose set forth.
